DD 

A two edged sword command which can be useful to backup whatever storage you have: hard disk, SSD, memory card, flash drive, CD, DVD, Blu-ray, whatever, and restore it later, or it can nuke your storages with no chances of recovery if you don't know what are you doing

DD can stands for Disk(s) Duplicator or Digital Duplicaton if you can harness it, but it can also stands for Damn Dangerous since it could be act as a Disk(s) Destroyer if you are clueless about this command, such as reversing input with output or forgetting to add sync command
